The Global Risks Report 2018 is published at a time of encouraging headline global growth.

Any breathing space this offers to leaders should not be squandered: the urgency of facing up to systemic challenges has intensified over the past year amid proliferating signs of uncertainty, instability and fragility.

This year’s report covers more risks than ever, but focuses in particular on four key areas: environmental degradation, cybersecurity breaches, economic strains and geopolitical tensions. And in a new series called “Future Shocks” the report cautions against complacency and highlights the need to prepare for sudden and dramatic disruptions.

The 2018 report also presents the results of WEF’s latest Global Risks Perception Survey, in which nearly 1,000 experts and decision-makers assess the likelihood and impact of 30 global risks over a 10-year horizon.

Over this medium-term period, environmental and cyber risks predominate.

However, the survey also highlights elevated levels of concern about risk trajectories in 2018, particularly in relation to geopolitical tensions.
